Set up local storage with InfluxDB

With InfluxDB®, you can store time series data from your devices locally. The purpose of local storage capability is to maintain operational visibility during network disruptions and reduce latency for time-critical applications. You can perform analysis and visualization at the edge while still having the option to selectively forward data to the cloud.

In this section, you create a time series bucket for turbine wind speed data and generate an API token for Grafana® and Node-RED® connectivity. The InfluxDB bucket serves as a dedicated storage container for your time series data, similar to a database in traditional systems. The API token enables secure programmatic access to your data.

To set up InfluxDB

  1. After completing the prerequisite steps and ensuring all tools are running on the same host, open your web browser and go to http://127.0.0.1:8086.

  2. (Optional) Enable TLS encryption for enhanced security. For more information, see Enable TLS encryption in the InfluxData Documentation.

  3. Create a time series InfluxDB bucket to store data from Node-RED. The bucket will serve as a dedicated container for your wind farm data, allowing you to organize and manage retention policies specific to this dataset. For more information, see Manage buckets in the InfluxData Documentation.

  4. (Optional) Configure the data retention period for your edge location. Setting appropriate retention periods helps manage storage resources efficiently by automatically removing older data that's no longer needed for local operations.

    For information about data retention, see Data retention in InfluxDB in the InfluxData Documentation.

  5. Generate an API token for the bucket. This token will enable secure communication between InfluxDB and other components like Node-RED and Grafana. This way, only authorized services can read from or write to your data store. For more information, see Create a token in the InfluxData Documentation.

After you complete these steps, you can store time series data in your InfluxDB instance, providing a foundation for local data persistence and analysis in your edge environment.
